HELPLIB.HLB  —  INSTALL  LIST
    Displays a description of each specified known image or, if no
    file is specified, all known images.

    Format

      LIST  [file-spec]

1  –  Parameter

 file-spec

    Names the file specification of an image installed as a known
    image. If you omit the file specification, INSTALL displays all
    known images.

2  –  Description

    You can use the LIST command with the /FULL qualifier to display
    information that is useful in tuning the known image database.
    For example, a high entry-access count for an image may indicate
    that system performance could benefit if the image were installed
    /OPEN. Similarly, high entry-access counts for an image may
    indicate that installing the image /SHARED-that is, with global
    sections-could improve performance. For a description of global
    sections and global pages, including information about how to
    estimate the size of installed images, refer to the OpenVMS
    System Services Reference Manual.

3  –  Qualifiers

3.1    /FULL

    Displays a multiline description of the specified known image,
    including the number of accesses, the number of concurrent
    accesses, and the number of global sections created. The /FULL
    qualifier with the /GLOBAL qualifier shows information about
    global sections, plus the current owner and protection codes and
    access control entries.

3.2    /GLOBAL

    Lists global sections for any specified shared image, or if you
    omit the file specification, lists all global sections. If a
    global section is created by INSTALL to support a particular
    image, that image is also identified.

3.3    /RESIDENT

    Displays a description of each resident image.

3.4    /STRUCTURE

    Lists addresses of known image data structures.

3.5    /SUMMARY

    Used with the /GLOBAL qualifier, displays the global section
    and global page usage on the system for local and shared memory
    global sections.

4  –  Examples

    1.INSTALL> LIST

    2.INSTALL> LIST/RESIDENT

      The command in this Alpha example displays a single-line
      description of all resident images. The description includes
      the location in memory, the size of the code sections, and the

    3.INSTALL> LIST/FULL LOGINOUT

      The command in this example displays a multiline description of
      the known image LOGINOUT.

            LOGINOUT;3       Open Hdr    Shar Priv

                Privileges = CMKRNL SYSNAM TMPMBX EXQUOTA SYSPRV 4

      1  Number of times known file entry has been accessed by this
         node since it swas installed.

      2  First number indicates the current count of concurrent
         accesses of the known file. The second number indicates
         the highest count of concurrent accesses of the file since
         it was installed. This number appears only if the image is
         installed with the /OPEN qualifier.

      3  Number of global sections created for the known file;
         appears only if the image is installed with the /SHARED
         qualifier.

      4  Translation of the privilege mask; appears only if the image
         is installed with privileges.

    4.INSTALL> LIST/GLOBAL

      The command in this example displays all global sections for
      shared images. Global sections created by INSTALL (prefix INS$)
      for a specific image are listed following the name of that
      image.

      1  Display of global sections in memory.

      2  Name of the image for which the following global sections
         were created by INSTALL.

      3  Name of global section. The prefix identifies the creator of
         the section; for example, INS means the global section was
         created by INSTALL. The number includes the address of the
         section.

      4  Version number (in hexadecimal) of global section; for
         shareable images only, the high-order byte (01 in CRFSHR_
         003) contains major identification, and low-order bytes
         (0003E8 in CRFSHR_003) contain minor identification
         determined by the programmer at link time. For executable
         images, the number is a known unique value determined by the
         system.

      5  Attributes of the global section:

         DZRO  Global section is demand-zero.
         GRP   Along with a group number indicates a groupwide
               section, which would be created by a program other
               than INSTALL.
         PRM   Global section is permanent.
         SYS   Global section is systemwide.
         TMP   Indicates a temporary global section, which would be
               created by a program other than INSTALL.
         WRT   Global section is writable.

      6  Number of pages (VAX) or pagelets (Alpha) in the section and
         number of page table entries currently mapped to this global
         section. For a more detailed discussion of mapping global
         sections, refer to the OpenVMS Programming Concepts Manual.

      7  Number of global sections created, number of global pages
         used, and number of global pages unused in local memory.
         Note that, because of arithmetic rounding, the number of
         global sections created will sometimes be greater than the
         SYSGEN parameter GBLSECTIONS. When the size of the system
         header is being computed, the values of the GBLSECTIONS and
         SYSMWCNT parameters are combined with the size of the fixed
         part of the process header. The result is rounded up to the
         next page boundary. This rounding process sometimes adds
         space to the global section table, depending on the values
         of the two SYSGEN parameters and the amount of system paging
         that preceded the running of INSTALL to create all of the
         global sections.

    5.INSTALL> LIST/GLOBAL/FULL

      The command in this example displays a complete listing of
      global sections for shared images. The /FULL qualifier adds
      owner and protection codes to the display.

          System Global Sections
